Abstract
To help enable the United Kingdom Food Standards Agency to protect the food chain in the event of an accidental
atmospheric release, it has funded the development of a puff dispersion model, called ADMS-STAR2, based on the existing ADMS
4. The ADMS-STAR2 model can be run using a range of input parameters or defaults within the model, dependant on the
information available following a release. Meteorological inputs include basic surface derived observational data or full 3-D
spatially and temporally varying NWP data. Thermal and explosive releases penetrating the boundary layer can be modelled. The
use of FLOWSTAR within ADMS-STAR2 allows consideration of complex terrain effects, with deposition responsive to spatially
varying surface roughness. Output options include isopleth display on ArcGIS of total ground deposition.
